Performance Per Dollar

The following chart may be the most interesting to many of you because it depicts the unit's performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. If the specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to USD (without VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU.

At the time we reviewed it, Corsair's RM750x sold for less than $100, allowing it to take the lead in our value comparison. PSU prices change frequently though, and with such small differences in overall performance, the SSR-750PX could easily lead in this chart if it became a little less expensive.
